There are a few areas where I see carbon capture viable: - Catching CO2 of unavoidable CO2 emitting processes, namely burning trash. In Europe we decided that we do not want landfills anymore, and what cannot be recycled has to be burned. We already start with a higher CO2 concentration, and have energy that is created while burning. Seems like a perfect opportunity for catching CO2. - Natural processes that catch CO2: Trees, olivine, ... - Systems for better indoor air with controlled home ventilation systems: I guess you will find people willing to pay for air with a lower CO2 content.
